Day 3

A not-very-tested version of the game is posted.

This update, I spent time trying to condense the objects down to children inheriting from parents and then using the variable options on the objects to set the stats for the towers.  After a lot of trial, that didn't pan out.  I followed a tutorial on how to use structures and got that going tonight.  Tower and Enemy stats are now set in a script file.

I also changed the resolution of the game to 800 x 600 and expanded the map a bit.  I also made it not possible to build towers over the menu oh and the ability to place multiple towers down instead of re-clicking the menu item.  I realize at writing this that those additional towers are currently free.  I will need to change that!

Next will be figuring out stats for all enemies and towers I think and getting them balanced.
